防止出現單邊未熔合。在填充焊絲時，應將焊絲送到熔池根部并向下輕壓一下，以保證根部熔透及根部內成形。（2）焊絲端部應始終處于氬氣保護之中，防止合金元素的氧化、燒損。為使熔渣盡快浮出，根據情況可用焊絲對高溫熔池進行適當攪拌，不宜依靠降低焊速來促使熔渣浮出。焊后在焊縫表面形成的熔渣薄而脆，高溫時極易自行脫落，故焊接時應戴好防護眼鏡，防止灼傷眼睛。（3）要獲得美觀均勻的焊縫很大程度上取決于正確掌握熔池的溫度。當發(fā)現熔池增大出現下凹，說明熔池溫度過高，這時應迅速減少焊與工件的夾角，并加快焊接速度。當熔池小焊縫窄而高時，說明熔池溫度低，這時應增大焊與工件的夾角，減慢焊接速度，蘇州異種合金連接焊條批發(fā)，減少焊絲添加量。（4）1Cr18Ni9不銹鋼在450~800℃溫度區(qū)加熱，常發(fā)生沿晶界的腐蝕破壞，稱為晶間腐蝕。為防止打底層焊縫金屬產生晶間腐蝕，應以快焊快冷為原則，盡量采用小的焊接熱輸入、快速焊、短弧焊、小幅擺動。（5）焊接時焊要等速移動，禁止抖動。焊絲與工件表面的夾角在25°左右，既可保證藥芯焊絲冶金反應的充分性，又可避免填充金屬的過熱，蘇州異種合金連接焊條批發(fā)。鎢極端頭與熔池表面的距離應保持在3mm左右，使操作者的視線寬廣，蘇州異種合金連接焊條批發(fā)，送絲方便，避免焊縫夾鎢。。藥皮在焊接過程中分解熔化后形成氣體和熔渣，起到機械保護、冶金處理、改善工藝性能的作用。蘇州異種合金連接焊條批發(fā)</p><div
